ADJUSTMENT INDICATOR AND CONTROLLER.

To all whom it may concern:

Be it known that 1, WILLIAM C. HUEBNER,

curate adjustment, for instance, the light box for the transparent positive or negative and the holder for the sensitized plate or stone in photographic printing machines, or

mechanism of a matrix-making machine.

The object of the invention is to produce a simple, reliable and convenient mechanism which enables. the adjusting movement of such and other adjustable machine parts to be arrested when the desired position has been reached. When the adjusting movement is effected by power the mechanism comprises preferably a clutch which connects the power with the adjusting mechaswitch for throwing the clutch intoaction, a controller which is set in accordance with the desired adjustment of the adjustable part, and mechanism which is controlled by the controller and acts automatically to throw the clutch out of action and stop the adjusting movement when the adjustable part reaches the desired position.

The adjustment sets of wheels or members, stationary but adjustable and is set to correspond with the desired adjustment of the adjustable part, and another set of which the wheels or members are driven in unison with the adjustable part so that the adjusting movement of such part is reproduced or represented by the movement of these driven wheels or members. Each set comprises a unit wheel or member and a fraction wheel The divisions, whether inches or centimeters, are marked on appropriate scales. The driven wheels or members are so connected with the adjusting mechanism that the unit wheel or member is driven a distance equal to one of thefiunit divisions unit of travel of controller comprises two one set WhlCll 1s Specification of Letters Patent.

the adjustable part, and the fraction member or wheel is driven the full length of a fraction scale which represents one unit of the unit'scale. When the adjustable wheels or members of the controller have been set for a desired adjustment and the adjusting mechanism has been started by closing the switch, the movement of the adjusting mechanism will continue until the driven members of the controller reach positions which coincide with the positions of the stationary adjustable members. wheels or members so coincide, electrical contacts are automatically connected and the clutch is thrown out of action, thereby stopping the movement of the adjusting mechanism.

I refer to like suitable mechanism, consisting, for instance,

of a screw D- which is connected by bevel gears 03 to the driven member of a clutch E.

The other member of the clutch is driven by gearscr' from a-main drive shaft F. The adjusting screw D is set in motionfor adjusting the carriage B and is stop ed by the clutch E. The clutch may be 0 any suit able construction but is preferably an electrical clutch in which the driven member is started and stopped by closing and-opening I an electric circult.

The holder C is adjusted vertically in the carriage by suitable mechanism, for instance, by screws 9 g, each connected by bevel gears h k to an adjusting shaft H on which. the

bevel gears h. are splined to permit of the] horizontal adjustment of the carriage. The shaft H is geared to the driven member of another clutch E, like the clutch E, which has a driving member geared to and driven by the drive shaft F by gears e a Fig. 1.

I represents the adjustment controller and indicator for regulating the horizontal ad-' justment of the carriage .B. Adjustment controllers of several different constructions but operating on the same principle are disclosed in the drawings.

In the construction shown in Figs. 19,

represents the controller casing, which is preferably provided with a glass face plate 21' and with hinged side portons i which can be opened to afford access to the controlling mechanism. K K K K represent four Wheels ormembers of which the wheels K K are driven in unison with the adjusting mechani'sm and K K are adjustable but stationary during the adjusting movement. These wheels are journaled concentrically one within theother on a supporting stud k in the casing i. The circular rims of these wheels are locatedjust in rear of the face' plate of the casing where they can be readily seen. Pointersk' k are provided on the front faces of the wheels K K, respectively, which cobperate-with'a stationary scale is which surrounds the Wheel K and may be formed on or secured to the face plate. Pointers k k are also provided on the wheels K K, respectively, which cooperate with .a stationary scale is surrounding the wheelK. The scale is? has equal divisions representing inches, centimeters .or

other units of measure which the carriage B travels horizontally, while the other scale is has divisions indicating small fractions of the units represented by the first scale. For example, the divisions of this scale, may in-.

. dicate two-hundredths' of an inch. The

wheels K and K are geared to the adjusting mechanism of the carriage so that the unit wheel K isturned a distance equal to one of the unit divisions of the scale is during a corresponding travel of the-carriage,

and the fraction wheel K is turned one complete revolution for each unit movement of the unit wheel K. The gearing shown for this purpose, F igs. 5 and. 7, consists of a gear rim is secured to the-hub of the fraction wheel K and meshing with a-pinion .70 on a' horizontal shaft k", and a gear rini Ir secured to the hub of the unit wheel K l nd meshing with a worm-'70 on a shaft is which is connected by bevel gears'kmto the horizontal shaft is". This shaft is conn ted by bevel gears 70 to an uprightsh'aft k? 1 'Which'is driven by bevel gears is from the adjusting screw D. "Any other suitable mechanism for driving the wheels K and K differentially, as explained, from the ad justing mechanism of the carriage could be employed. The two stationary but adjust ablewheels K and K can be independently set or adjusted to any desired position, for lnstance, by gear rims Z and Z secured respectively to the hubs of the wheels-K and K and meshing with pinions Z and l onadjusting shafts l l which are provided with hand wheels Z Z for turning them. M, Figs. 4 and 6, represents a contact device secured to the controller casing and hav 7 ing a wheel wa or part bearing'against a conducting ring m which is secured to and insulated from the gear rim of the driven unit WheelK. Alcontact M secured to this. ring is adapted to engage a-cooperating contact M carried by a conducting ring m which is secured to and insulated from the gear rim of the adjustable unit wheel K This ring m revolves in engagement with a contact a M? which is carried by 'and insulated from the gear rim of .the driven fraction wheel K The contact M is adapted to engage a contact M carried by a conducting ring m which is secured to and insulated from the 7 gear rim of the adjustable fraction wheel K. A stationary contact device M on the casing 2' has a wheel m or other suitable part bearlng against this conducting ring m.

, The terminals of the solenoid winding are connected, respectively,

to one-side, n, of the clutch circuit and to the contact M of the adjustment controller, while the other contact M of the controller, is connected by a conductor a to the other side of said circuit. Consequently, when the contacts M and M are electrically connected by the operation of the controller, the solenoid n will be energized and will move the switch N to open the clutch circuit and stop the clutch driven mechanism. 0 represents an adjustment controller similar to that described which operates in the same manner to automatically control the operation of the clutchdriven adjusting mechanism for the holder driven adjusting mechanism for the holder C.

In the modified construction of the con-' troller shown in Figs. 10-12, P represents the controller casing and P and l? repre" sent respectively, the driven unit and fraction members which consist of rotating arms driven at diiferential, speeds by suitable gearing connecting them with the clutchdriven adjusting mechanism. P and P represent respectively, the adjustable unit and fraction members which consist of pointers cooperating with appropriate scales on the controller casing and are provided with clamp nuts p' p for securing them in adjusted positions in slots p in the controller casing. The driven members are provided with contacts Q Q, respectively, and

stationary wheels K and K the con- 7 unit and fraction wheels K and K s shown in Fig. 4, the clutch E the adjustable members are provided with contacts Q Q respectively. The contact Q travels in contact with a conducting ring 9 connected to a stationary contact device Q on the casing and is adapted to engage the adjustable contact Q The latter and the driven contact Q bear against a conducting ring a and the contact Q is adapted to engage the other adjustable contact Q} which bears against a conducting ring (1* connected nism into engagement with the contacts Q and Q, they will place the stationary contact devices Q and Q in electrical connection, which will stop the clutch-driven adjusting mechanism in the manner beforev described in connection with the controller I.

In the modified construction shown in- Figs. 13-15, the driven unit member is secured directly to and travels with the adjustable carriage B and carries a contact R which is adapted to engage the contact R of the adjustable unit member. This member is adjustable on a unit scale bar r secured to the stationary frame ofthe machine. The

driven fraction member consists of a wheel. 1' whlch 1s provided with a contact R and is driven at the proper speed by gears 7 connectingit with a toothed rack r on the carriage B. The contact R is adapted to be adjusted to the correct fractionalpo'sition on this wheel by reference to a fraction scale 1' on the wheel. This contact R is adapted to engage a fixed contact R. The contacts R and R are connected to a device for opening the circuit of the driving clutch of the adjusting mechanism. The contacts R? and R 1 are adjusted to indicate, in inches or other units, and fractions thereof, the desired adjustment. and when the contacts R and R engage the contacts R and R the latter will be electrically connected and will operate to stop the clutch-driven adjusting mechanism in the manner before described.

It will be evident from the three constructions of the adjustment indicator and controller describedthat the controllers can beconstructed in different ways and'still operate on the same principle to insure the adjustment of an adjustable part or device accurately to a very small fractional part of an inch or other unit of measure. By constructing the controller on the described principle, with. the separate adjustable and driven unit and fraction members, a fraction scale with large divisions can be used and this enables the adjustable members to be set quickly and easily and still insure an extremely accurate adjustment.

While the device is preferably used as an automatic controller in the manner exthe adjusting movement.

plained, it can also'be used without auto matic controlling mechanism, in which case thedevice indicates to the operator of the machine when, the desired adjustment has been reached but does not automatically stop When the device is used without this automatic mechanism, the adjustable unit and fraction wheels or members are set to correspond with the desired adjustment of the movable part of the machine, the adjusting mechanism of such movable part is operated by hand orpower, and the driven unit and fractlon wheels or members are actuated in unison with the adj ustable part,; as. described, and indicate to the operator, by their movement and by comparison with the adjustable but stationary members or Wheels, when the ad usting,

movement has placed the adjustable machine part in the desired position.- When this position has been reached the driven unit and fraction wheels or members coincide exactly with the adjusted position of the adjustable unit and fraction wheels or members and the operator stops the adjusting movement.
